7 Weeks Pregnant: Your Baby’s Development

Brain child. Although brain development will continue long after birth, the basic sections have formed. As the week progresses, this organ will divide into three parts: forebrain, midbrain and hindbrain. The forebrain will be responsible for things like reasoning, problem solving and forming and retaining memories. The midbrain will relay electrical signals to their final destinations in the brain. The hindbrain will take care of breathing, heart rate and muscle movement. Limbs are also growing fast: arm and leg buds have sprouted.

Measuring up. Your little one is 0.15 to 0.3 inch (four to eight millimeters) long this week, a little larger than the width of your pinky nail.

7 Weeks Pregnant: Your Symptoms

The pee parade. Raging hormones and increased blood volume cause your body to produce more fluid, so you may find yourself heading to the ladies’ room more often than before. However, it’s important to stay hydrated - you should continue to drink extra water throughout your pregnancy.

Healthy habits. Make sure to order your meat well done and avoid kitty-litter duty throughout your pregnancy. Toxoplasmosis, an infection passed along through raw meat and cat feces, can be harmful to your fetus (but not to you). In fact, you may have already had it without knowing it - if so, you are immune.

Did you know? The areas of the baby’s brain are beginning to form and the buds that will become arms and legs are sprouting. The ears and tip of the nose can now be seen.
